The present disclosure relates to a flexible pipe body for conveying high pressure fluid. The flexible pipe body comprises a tubular fluid sealing layer, a pressure retaining armour layer positioned over the tubular fluid sealing layer, and a tensile armour layer positioned over the pressure retaining armour layer. The tubular fluid sealing layer comprises a composition comprising a plasticizer and a homopolymer of vinylidene fluoride, and wherein said plasticizer is present in an amount of 0.3 to 2.0 weight % based on the total weight of the polymer composition. La présente divulgation concerne un corps de tuyau flexible permettant de transporter un fluide à haute pression. Le corps de tuyau flexible comprend une couche tubulaire d'étanchéité aux fluides, une couche d'armature de maintien de pression positionnée sur la couche tubulaire d'étanchéité aux fluides, et une couche d'armature tendue positionnée sur la couche d'armature de maintien de pression. La couche tubulaire d'étanchéité aux fluides comprend une composition contenant un plastifiant et un homopolymère de fluorure de vinylidène, et ledit plastifiant est présent en une quantité comprise entre 0,3 et 2,0 % en poids sur la base du poids total de la composition de polymère.
